SPECIFICATION forming part of Letters Patent No. 782,549, dated February 14, 1905.

I A Application filed May 28,1904. Serial No. 210,270.

To all whom, it ntay concern:

Be it known that we, JOHN MAURY Dovn, residing at Washington, in the District of Columbia, and JOHN SnLLnRs BANCROFT and- MAURI'IZ C. INDAHL, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, citizens of the United States, have invented certain new and useful .Improvements in Die-Case-Transposing Mechanism for Type-Machines; and we do hereby declare the following to be a full, clear, and

- exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the figures of reference marked thereon.

This invention relates to that class of typemachines in which a die-case equipped with a plurality of matrices is adjusted by a centering mechanism to bring any desired matrix opposite the mold, as in the type casting and composing machines of the Monotype and has been found necessary to restrict the ca pacity of the machine, as represented by the number of available characters or matrices, within somewhat narrow limits, in order to attain the requisite speed of production and at the same time maintain the quality up to the standard. In other words, capacity is subordinated to speed and quality, in so far as the automatic action of the machine is concerned, and when it is desired to produce characters other than those represented by the matrices of the die-case with which the machineis at the time equipped the die-case must be removed and its matrices replaced by others containing the desired characters, or, what is more usual, another die-case substituted. Heretofore the substitution or interchange of die-cases has been effected manually by the operator at the casting-machine, involving a considerable loss of time both at the castingmachine and the keyboard; but the most serious defects are those incident to the fact that the changes from one set of matrices to another are not withinthe immediate control of the person responsible for the matter turned outthat is, the compositor who prepares the record-strip which governs the automatic action of the casting-machine.

Now the primary objects of the present invention are to increase the capacity of the casting-machine with respect to the number of characters or matrices automatically controlled thereby without imposing additional burdens upon the translating or adjusting devices, such as would interfere with the speed of production, and to materially enlarge the control exercised by the compositor of the recordstrip over the product of the casting-machine; to which ends the said invention consists,' broadly, in the use of an automatic die-case-transposing mechanism for efiecting an interchange of die-cases with the centering mechanism or translating devices of thecasting-machine, in the use of the record-strip for controlling the actions of said transposing mechanism, and in certain novel constructions, combinations, and arrangements of parts, all as hereinafter fully described, and the novel features pointed out in the claims.

In the accompanying drawings, illustrating a preferred form of embodiment of the invention, Figure 1 is a top plan view of a castingmachine,showing the application thereto of the die-case-transposing mechanism. Fig.2 is a top plan View of the transposing mechanism shown on an enlarged scale. Fig. 3 is an end view ofthe attachment, showing also the connection with the paper-feed. Fig. 4 is a side elevation, partly in section, of the mechanism for elevating the die-case-supporting frame to disengage the die-case from its translating devices or centering mechanism and to retract l centering-pin advancing to finally center the the centering-pin.

Fig. 15 is aside elevation of the die-case. Fig. 16 is a diagrammatic View showing the pneumatic control system and a section of the record-strip.

The same numerals designate like parts in the several figures.

The type-casting machine illustrated in part is essentially that of Patent No. 625,998, to which latter reference may be had for the details of construction and mode of operation, as only those parts with which the new attachment has direct connection are shown-such as the main frame 1, the paper-feed 2, the mold 3, the bridge 1, in which are mounted the vertically-movable supporting-frame 5 for the die-case carrier 6, the centering-pin 7 the actuating-lever 8 for the die-case-supporting frame, the centering-pin lever 9, the die-case-' centering mechanism 10, the main drivingshaft 11, the perforated record-strip 12, and the die-case 13. As contributing to a clearer and more ready understanding of the attachment it mayhere be remarked that the centering mechanism 10 includes two adjusting or positioning systems independently controlled from the record-strip and acting the one upon the die-case 13 and the other upon the die-case carrier 6 to center any matrix above the mold by a two-Way movement of the die-case, to which end the latter is mounted to reciprocate upon its carrier in a direction at right angles to the movement of the carrier upon the supporting-frame 5. The diecase is detachably connected to its section of the centering mechanism, as by being provided with a recess 15, Fig. 15, to receive bar 16, Fig. 12, on the centering mechanism, so that by elevating the supporting-frame 5 above its normal or working position the diecase will be uncoupled and can be Withdrawn or inserted, as desired. The centering-pin lever 9 isso coupled with the centering-pin 7 and the die-case-supporting frame that upon the descent of said lever the supporting-frame, and with it the die-case, will be depressed to seat the selected matrix upon the mold, the

selected matrix and hold it firmly. in contact with the mold while the cast is being made.

In the preferred form of embodiment herein illustrated the automatic die-case-transferring attachment occupies a position on the front side of the machine above the galley mechanism and comprises a magazine or die-case holder for accommodating a plurality of diecases, a selective mechanism for presenting the die-cases in position to enter the die-case carrier, automatic means for uncoupling and coupling'the die-case and its centering-mechanism, translating devices for moving the selected die-case into and withdrawing the same from the carrier, and a starting mechanism together with other features contributing to the end in view, as will presently appear.

The magazine or holder is represented as a turret or head 17, Figs. 3, 8, and 12, preferably polygonal in section and provided with a series of parallel sets of guides 18, forming receptacles for supporting the die-cases. This head 17 is revolubly supported on the outer end of a frame 19, as by being attached to a shaft 20, mounted in a bearing on said frame and provided with a pinion 21, through which motion is communicated to the head. The frame 19 is pivotally supported at its inner end on a shaft 22 in line with or constituting a prolongation of the axis of centering-pin lever 9, and it is coupled by a link 23 to an actuating-lever 2 1, engaged by a cam 25, loose on shaft 26, through which motion is transmitted to said frame for elevating and depressing the magazine. Each die-case is furnished with a notch 27, Fig. 15, in its central guide for receiving a circumferential projection or flange 28, surrounding the bearing for shaft 20, said projection being provided with a gate,

IOC

as at 29, opposite the point at which the diecases are received or discharged to permit the passage of the central guide, so that when a die-case has been inserted in the head and as the latter is revolved or oscillated the flange 28 will enter its notch 29, and thus lock the die-case in position and prevent accidental displacement. As a matter of accommodation for other; parts of the machine and to insure the proper presentation of the die-case to the translating mechanism when brought into position to be transferred to the die-case carrier it has been found desirable that the diecases should be shifted slightly during the rotation of the magazine, and as they approach toward and depart from the gate 29, to which end the flange 28 is deflected to one side in'the immediate vicinity of the gate, as illustrated in Fig. 14, wherein said flange andits sleeve are shown in reversed position to correspond with that of the die-case, Fig. 15.

The selective mechanism controlling the magazine and the presentation of the die-cases in position to be transferred to the die-case carrier of the casting-machine is represented in the present instance bya series of gage or stop pins 30, Figs. 8, 10, and 11, one for each die-case, governed by special perforations or signals in the record-strip and operating in conjunction with the magazine-shifting mechanism to determine the extent of motion to be imparted to the magazine. Hence the positions assumed by its receptacles or guides 18 1 relative to those of the die-case carrier and also as a locking means for holding the magazine 17 in adjusted position during certain intervals,as will presently appear. In the illus- 1 tration the head 17, rectangular in section, is

equipped with four sets of guides 18. Hence four gages are employed, each corresponding with one set of guides 18, and as according to this arrangement said guides are arranged at equidistant points about the circumference of the head the gages occupy corresponding positionsthat is,they are serially arranged at equal distances apart. Each gage is attached to a piston 31, the latter working in a cylinder in the frame 19 and provided with a retracting-spring and an inlet 32, the latter communicating with a port 33, Fig. 16, of the paper-feed mechanism. Supported to reciprocate longitudinally in guides on frame 19 in a plane parallel with the series of gages 30 are two oppositely-movable jaws 34 35, adapted to engage and close upon any one of the gagles 30 when the latter is projected into their pat 1. I

The means devised for actuating jaws 34 35 in relatively opposite directions to open for receiving a gage and to close upon the latter irrespective of the .position it occupieswithin the range of their movement includes two racle bars 36 37, one for each jaw, and preferably formed integral therewith; a longitudinallymovable rack-bar 38, supported in guides on frame 19, parallel with. rack-bars 36 37, and two pinions 39 40, each engaging one of the rack-bars 36 37 and both engaging rack-bar. 38.

bearings lixed to frame 19, while pinion 39is- Pinion 40 is mounted to rotate in or on carried by a link 41, provided with a spring compression box or coupling 41 andattached to an actuating-lever 42, the latter engaging til one of them is arrested by contact with the gage, after which the opposite jaw will be advanced until arrested by contact with the stationary jaw on the opposite side of the gage. During this action the jaws may advance"suc cessively or simultaneously, depending upon their relative resistance. Thus if the resistance of jaw 35-is in excess rack-bar 38 will remain stationary when pinion 39 begins its motion. By virtue-of its contact with rack-bar 38 the upper portion of pinion 39 will be rotated in the direction of its bodily movement and the jaw 34 will be advanced until it contacts with the projected gage 30, thereby arresting the further motion of rack-bar 36, whereupon the latter will replace rack 38'as the fixed member for effecting the rotation of pinion 39, and as said pinion continues its advance rack-bar 38 will be moved in the same direction and acting through pinion 40 will cause jaw 35 to approach and close upon the gage 30. Should the resistance of jaw 34 be in excess, its rack-bar 36 will remain at rest while pinion 39 acts thereon to move rack-bar 38 and advance jaw 35 until it contacts with the gage, whereupon rack-bar 38 will be held in position while pinion 39 acts thereon to advance jaw 34. Each jaw 34 35 is permitted a range of motion somewhat in excess of the space occupied by the series of gages 30, and by the use of the rotary reciprocating pinion 39 in connection with the oppositely-disposed movable rack-bars the motion of the driving member or link 41 may be multipliedv to such an extent that a comparatively short excursion of said link will suffice. One or both jaws 34 35 is furnished with a lip or projection 34 which enters a notch 30 in the stoppin or gage 30, when the jaws closeupon the latter to prevent the withdrawal of the gage until the jaws again open. To render this controllable gaging mechanism operative upon the revoluble magazine or head 17, a rack-bar 45, guided on frame 19 and engaging pinion 21, is furnished-with a head or projection 46,

occupying a position between and in the path of jaws 34 35, so that as they are operated in the manner described to close upon one of the gages 30 they will at the same'time engage .and withdrawal of the diecase in its carrier 6 is effected through the medium of an extens'ible connection intermediate the actuating-lever 8 and the centering-pin lever 9 from which it receives motion. The lever 9 is formed in two parts, a driving-section 47, attached to. the dependent member 48, upon which the actuating cam operates, and a loosely-pivoted section 49, the latter extending through a slotted bearing 50 on section 47 and engaging the centering-pin. When the machine is in operative conditionthat is, adjusted for casting typethe two sections 47 and 49 of lever 9 are locked together as one by the insertion of a block 51 within slotted bearing 50 above section 49, so that the two sections will operate as the integral lever of the prior machine. The block 51 is guided upon section 49 to reciprocate longitudinally thereof and is of proper dimensions to fill the interval between section 49 and the upper end of bearing 50 when section 49 is seated upon the lower end of said bearing, the front upper edge of the block being beveled to facilitate its entrance into the slot. The position and movements of block 51 are controlled by a cam 52, loose on shaft 26, acting through lever 53 and link 54. To section .49 of lever 9 is pivotally attached a three-.

armed member or lever 55, forming part of the extensible connection, with one arm, 56, extending through slotted bearing 50 and connected to the link 57 on the die-ease-support lever 8, a second arm, 58, projecting upward in rear of block 51, and a third arm projecting downward in the plane of a supportingsurface 59 on the bridge 4. The maximum vertical dimension of arm 56 within the slotted bearing 50 corresponds with that of section 49, so that when block 51 is interposed the lever 55, as well as section 49, will be rigidly locked to section 47, as seen in Fig. 5; but when said block 51 is withdrawn from bearing 50 not only will section 49 and lever 8 be released, but owing to the engagement of block 51 with arm 58 lever will be tilted to actuate lever 8 and engage surface 59, thereby elevating the supporting-frame 5 to uncouple the die-case from its centering mechanism and at the same time providing a support for section 49, connected to the center ing-pin to prevent the latter from following the motion of section 47 as the latter reciprocates.

As the locking of the paper-feed-actuating devices accompanies the withdrawal of block 51 and is connected therewith it is appropriate that the means for effecting this action should be explained at this point. Upon the bearings or supports for lever 9 and above the latter is mounted a rock-shaft 60, Figs. 2, 3, and 4, carrying an arm 61, the latter coupled by a link 62 to the locking-lever 63 of the paper-feed mechanism. This lever 63 controls the holding-pawl of the paper-feeding devices and when turned in one direction locks the latter against movement by the feeding-pawl. Shaft is also provided with an arm 64, engaging an adjustable coupling on the link 54, through which motion is communicated to block 51, the arrangement being such that when said block is withdrawn to elevate the die-case carrier the paper-feed will be locked out of action and so retained until the block is again advanced to couple the diecase with its centering mechanism and lock the two sections of lever 9 together, thus placing the machine in condition for casting. Link 62 is also utilized to hold the air-bar down and admit pressure to the exposed ports during the time the paper-feed is locked out,

for which purpose it is provided with a beveled surface 65, which rides over the liftingpin 66 on the air-bar lever 67.

' It is while the die-case carrier occupies the position to which it is shifted by the withdrawal of block 51-that is, a position wherein the die-case is uncoupled from its centering mechanism-that registry is effected between its guides and the set of guides 18 of the magazine corresponding with and designated by the gage 30 at the time in action. Suitable means are provided for insuring accurate registry of the guides, as by providing the carrier with an inverted-V bearing'68 in position to receive a complementary bearing 69, carried by frame 19.

The translating mechanism operates to restore the die-case previously in use to its compartment in the magazine, and after the latter has been adjusted to transfer the selected diecase to the die-case carrier in position to be coupled with its centering mechanism when the mechanism of the casting machine is restored to working condition. A sample mechanism of this kind is shown as mounted upon frame 19 and controlled by cams loose on shaft 26. The die-cases 13 are each provided with a series of rack-teeth 71 along one edge, and the frame 19 is equipped with a supplemental frame 72, supporting shafts 73, each of thelatter carrying a wheel 74 for engaging the teeth on the die-case. One of each set of guides 18 is provided with lateral openings for the passage of the wheels 74, and the frame 72 is pivotally attached at its upper portion to a shaft 75, mounted in bearings on frame 19 and extending parallel with the axis of head 17. Frame 72 is furnished with an arm 76, and the latter is coupled with the actuating-lever 77, engaging cam through a link 78, whereby said frame is oscillated to carry wheels 74 into engage ment with the teeth onythe die -case for moving the latter or to withdraw them therefrom for shifting the position of the magazine. Shaft 75 is connected to each of the shafts 73 through bevel-gears 79 and is furnished with a pinion 80, engaging the teeth of a rack-bar 81, connected by a link 82 to an actuating-lever 83, engaging a cam 84, loose on shaft 26. Cams 70 and 84 are so formed, proportioned, and arranged that when the magazine is elevated and until the frame 19 is lowered to bring a pair of guides 18 into alinement with thoseof the die-case carrier no motion will be transmitted to the parts connected therewith the frame 72 being at the time so held that the wheels 74 are withdrawn from head 17 and the rack-bar 81 retracted. As soon, however, as the guides are brought into alinement, block 51 having in the meantime been withdrawn to elevate the die-case carrier, frame 72 is swung toward head 17, as shown in Fig. 8, and immediately thereafter rack-bar 81 is advanced to rotate wheels 74 in a direction to transfer a die-case from its carrier to the magazine.

' movement has been completed and while rackcam to permit rotation of head 17 under the influence of cam 13 to the position designated by one of the gages 30, after which the frame 19 is again lowered and frame 72 swung back to engage the wheels 7 1 with the selected die case, and cam 84 retracts rack bar 81, thereby reversing the motion of wheels 74: and transferring the die-case to its carriage, after which cam again swings frame 72 outward and frame 19 is elevated, thus completing the cycle. The several cams are united to rotate in unison and the cam-cylinder thus forined is loose upon shaft 26, the latter being connected to the driven'cam-shaft of the castingmachine through a gear-train by which the speed of shaft 26 is diminished to about onefifth or other desired proportion of the driven cam-shaft.

Shaft 26 has secured thereto one member of a clutch in the form of a ratchet-wheel 86, Fig. 13, in position to be engaged with an opposing clutch-section in the form of a pawl 87 carried by the cam-cylinder. This'pawl is provided with a spring 88 tending to engage it with the driving ratchet-wheel 86, and it is held therefrom by a shoulder 89 on a lever 90 engaging the tail 'of the pawl. Thelever 90 is furnished with a second shoulder 91 in position to engage a pin 92, carried by the cam-cylinder for preventing back motion of the latter. Lever 90 is held normally by a spring with its shoulder 89in engagement with pawl '87 to hold the latter removed from the driving ratchet-wheel 86 and its shoulder 91 behind pin 92 to prevent retrograde movement or displacement. By a movement of lever 90 in a direction to withdraw shoulder 89 from pawl 87 the latter is released and immediately caused to engage ratchetwheel 86, thus putting in motion the cam-cylinder, and the latter continues in action until upon the completion of one revolution pawl 87 reengages shoulder 89 and is thereby withdrawn from the ratchet-wheel.

The starting of the attachment into action by coupling the actuating devices with the vdriving mechanism is controlled from the After this rival of pawl 87 opposite shoulder 89 on lever 90, so that the latter will return to engaging position when the record-strip is advanced during the last revolution of the main driving-shaft. i

In order that this attachment may operate in harmony with the casting-machine to which it is shown applied, it is requisite that the die-case and its carrier should occupy a fixed predetermined position at the time the transfer of die-cases is to be effected, and this may be attained by associating with the starting andgaging perforations the necessary positioning-perforations for acting, through the centering mechanism, to locate the die-case and its carrier in the desired positions. Thus in the diagrammatic view, Fig. 16, the signal for the transfer of die-cases is composed of two positioning-perforations 96 97, pertaining to the die-case-centering mechanism, a startingperforation 98, and a die-case-selecting'perforation 99. After the last type designated by the signal preceding thedie-case-transfer signal has been cast and while the transfer of, die-cases is being effected the action of the pump should be suspended to prevent the injection of molten metal into the uncovered mold.

A lock-out mechanism suitable for the purpose and adapted to the pump-actuating devices of the prior patent is indicated in Figs. 2 and 3, wherein the pump-disengaging rod 100 (numbered 240 in the prior patent) is engaged by a bell-crank lever 101, attached to a rod 102, extending back to a cam 103, the latter serving to moverod 100 in a direction to disconnect the pump and to so hold it until just before the cam-sleeve completes its rotation.

A full and clear understanding of the general operation of the die-case-transfer mechanism will be found in the following brief sum mary of the cycle of operations as produced and controlled by the cams 25, 43, 52, 70, 84, and 103. When the casting-machine is in operation, the die-case-transposing mechanism is at rest with its magazine sustained in elevated position and the cam-cylinder disconnected from its driving-shaft. At this time the lower set of guides are empty, the die-case belonging'theretohaving been transferred to the diecase carrier, and the magazine is locked in position by the engagement of the jaws 34 35 with projection 16 and the gage-pin 30 corresponding with the die-case at the time in the carrier, for which purpose the cam 43 is properly shaped to hold pinion 39 in advanced position, with the coupling 41 under sufficient compression to maintain the jaws in closed position, while the magazine is elevated. The die-case-transfer signal for bringing the transfer mechanism into operation is formed by the compositor at the key board-perforator, who designates the particular die-case to be used for succeeding characters by forming the four perforations constituting the transposition-signal in the recordstriptwo for positioning the die-case and its carrier, one for starting the transfer mechanism and another for designating which one of the die-cases is to be used for the next succeeding character represented in the record-strip. When this transfer-signal arrives beneath the air-bar and the latter is depressed, pressure is admitted to the ports uncovered by the perforations. The main driving-shaft continuing in motion, the type previously designated is cast, the stop-pins of the primary gages of the die-case-centering mechanism are set, starting-lever 90 is operated to connect the cam-cylinder to its drivingshaft 26, and pressure is admitted to the cylinder of the gage 3O designating the die-case which is to be next used. At the time the newly-designated gage 30 cannot advance, as jaws 34 35 are-closed, and it is not until later, when they open, that it takes its place between them. The cam-cylinder having been started in motion, but at a slower rate of speed than the main drive-shaft, cam 25 lowers the magazine 17; but before this is fully accomplished the centering mechanism has brought the diecase and its carrier to the position indicated by the two positioning-perforations, and cam 52 has withdrawn block 51 to elevate the diecase and its carrier and lock the feeding devices and air-bar in position. lmmediately the magazine engages the alining projection on the carrier cam 43 operates to open jaws 34 35, allowing the gage 30 previously held between them to retract and the gage under pressure to advance, and at the same time shortly thereafter cam 7 0 operates to swing the gear-frame inward, bringing the first gearwheel into mesh with the teeth on the die-case at the time in its carrier. Cam 84 next operates to advance rack 81, thereby rotating the wheels in a direction to withdraw the die-case from its carrier and deposit it in the empty berth in the magazine. Thereafter cam' 25 raises frame 19 sufficiently to cause the magazine to clear the mechanism below it and cam 7 0 again swings the gear frame outward. This releases the magazine, so that it is free to rotate, whereupon cam 43 closes the jaws upon the gage 30 and swings head 17 to the new position. Frame 19 is again lowered through the medium of cam 25 and the gear-frame swung inward by cam to engage the wheels with the selected die-case, after which cam 84 retracts rack-bar 81, rotating the wheels in the Opposite direction and transferring the die-case from the magazine to its carrier. The transposition of die-cases having thus been completed cam 52 advances block 51 to lower the new die-case into engagement with its centering mechanism, connect up the two sections of the centering-pin lever, and release the paper-feed mechanism, while cam 25 elevates the magazine and cam 7 O swings the the gear-frame outward. After the paper-feed lock has been withdrawn and before the magazine is fully elevated the paper-feed mechanism operates to ad vance the record-strip,thereby releasing the starting-lever and permitting it to resume its position in the path of pawl 87 so that as the latter continues to advance it will be engaged and withdrawn from the driving member of the clutch and the cam cylinder brought to rest, thereby completing a cycle of operations as performed by the die-case-trans posing mechanism. 4 Viewed in its practical and commercial aspects the importance and advantages of an automatic die-case-transposing system of this kind will be apparent when it is considered that the number of characters or matrices thus placed at the disposal and underthe direct control of the compositor increases with v cases two interchangeable die-cases with an 5 aggregate capacity of four hundred and fifty matrices will suffice.

We believe ourselves to be the first to provide a type-casting machine with a plurality of interchangeable die-cases and automatic means for selectively coupling individual diecases with the centering or positioning mechanism and to control the selection and coupling of the die-cases through the medium of a record-strip. Hence we wish it clearly understood that our invent-ion is not limited to the particular apparatus herein described, as the latter represents but a preferred form of embodimentillustrativeof the principleinvolved.

Having thus described our invention, what we claim as new, and desire tov secure by Letters Patent, is
